Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19058, here are decompositions:

7 + 19051 = 19058
79 + 18979 = 19058
139 + 18919 = 19058
199 + 18859 = 19058
271 + 18787 = 19058
367 + 18691 = 19058
379 + 18679 = 19058
397 + 18661 = 19058

Showing the first eight; more decompositions exist.
